Here's why:
* "Nwannem" means "my brother/sister" and is used to address a close friend or family member.
* "Kekwa" is not a word in Igbo, but it sounds like it might be a mispronunciation or misspelling of "kwere," which means "to believe."
* "Nu" is a question particle in Igbo.
Therefore, the phrase is incomplete and lacks a subject for the verb "kwere." It's like saying "My brother believes... what?"
To make sense of the phrase, we need more context. Here are a few possibilities depending on what the speaker intended:
* "Nwannem, kwere nu?" (My brother, believe this?) - This would be a question asking someone to believe something specific.
* "Nwannem kekwa" (My brother, believe) - This would be an incomplete phrase, maybe followed by a statement or request.
* "Nwannem, kekwa nu" (My brother, believe this one) - This would be a phrase where "nu" refers to a specific person or thing, but it's still grammatically incorrect.
Without more information, it's impossible to give an accurate translation.
